A New Kind of FDM/FEM Squeeze Casting Temperature Field Calculation Model

摘要：

　　A new FDM/ FEM model is developed to simulate the temperature field during the solidification process of squeeze casting.So we can transform the FDM mesh into FEM mesh directly,then established the relationship of pressure change and melting temperature change and correct the size of melting temperature value and other thermal physical parameters (such as the thermal conductivity)which is related to the temperature,and establish the temperature and thermal physical parameter relationship to get a data base.The solidification process of AM50A magnesium alloy is simulated.Squeeze casting experiments are also incited for validating the new FDM/FEM model.It is shown that the results of numerical simulation are in agreement with the experimental results.
